Guest Shadow Posted June 24, 2008 Posted June 24, 2008 My samsung sh-182f DVD writer has become horribly slow, records at 1X max, even with 16X disks. I cannot turn DMA on in the hardware manager. Even my floppy drive has DMA ........ Must be a way. 6 hours hacking and nothing so far. TIA Apparently there is a registry/system entry that does not allow DMA on a drive, but cannot find it. Neither on PC or on Google. The drive had DMA a month ago, last time I checked.

Is UDMA enabled for the IDE channel the drive is on? What happens when you try to enable DMA in Device Manager? Are there any problems noted in Device Manager?

Open Device Manager, select the top entry (Computer icon), and click the Properties button. This will display the IRQ settings. Select Direct Memory Access(DMA) to view devices using DMA Channels. What DMA Channels are in use? There are 8 DMA channels but one is used by the DMA controller so 7 are available for devices. Tell us what device is using each channel. Uninstall the Via chipset drivers (4-in-1 driver). Reboot. Then restart in Safe Mode. Open Device Manager, remove all items in the CDROM category, remove all items in the Hard disk drives category, and remove the VIA Bus Master PCI IDE Controller in the Hard disk controller category. Restart in normal mode, let Windows redetect both the primary and secondary IDE controllers, then reboot and install the Via 4-in-1 drivers. If that does not help, replace the IDE ribbon cable attached to the DVD drive with a new one no more than 18" long. Repeat the above steps if needed. In looking at the info you posted in reply to PCR, I notice you have viamvsd.vxd and VIAmraid.mpd installed. Those are Via RAID controller drivers....are you using the RAID controllers? If not, why are you enabling them and installing drivers? -- Glen Ventura, MS MVP Windows, A+ http://dts-l.net/ http://dts-l.net/goodpost.htm

I see nothing about raid in the bios. When I enable dma in device manager, it writes this : [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\hdc\0002] "DevLoader"="*IOS" "DriverDesc"="Secondary IDE controller (dual fifo)" "InfPath"="VIAVSD.INF" "InfSection"="VIAIDE" "PortDriver"="ESDI_506.pdr" "ProviderName"="Microsoft" "DriverDate"="2001\\10\\18" "IDEDMADRIVE0"=hex:01 "IDEDMADRIVE1"=hex:01 "AutoInsertNotificationDrive0"=hex:01 Does that look ok to you ?

My understanding is that IDE devices connect to a "bus mastering" controller which accesses system memory directly rather than by using the motherboard's DMA controller chip. Hence Device Manager will not show any DMA channels for the hard disc controller. See http://en.wikipedia.org/wiki/Direct_memory_access ===================================================================== A DMA transfer essentially copies a block of memory from one device to another. While the CPU initiates the transfer, it does not execute it. For so-called "third party" DMA, as is normally used with the ISA bus, the transfer is performed by a DMA controller which is typically part of the motherboard chipset. More advanced bus designs such as PCI typically use bus mastering DMA, where the device takes control of the bus and performs the transfer itself. ===================================================================== - Franc Zabkar -- Please remove one 'i' from my address when replying by email.

Yes. It shows DMA enabled for both Secondary IDE Channels. I am starting to think the drive itself is going bad. -- Glen Ventura, MS MVP Shell/User, A+ http://dts-l.net/ http://dts-l.net/goodpost.htm

According to IBM's Technical Reference manual for the PC AT, the original AT had two DMA controllers (Intel 8237A-5) which could each handle four DMA channels. As was the case with its two interrupt controllers, the output of the first DMA controller was cascaded into the second DMA controller. The manual states that "DMA channels 0,1,2, and 3 are used for 8-bit data transfers, and channels 5,6, and 7 process 16-bit transfers. Channel 4 is used to cascade channels 0 through 3 to the microprocessor". So what you are seeing as "04 Direct memory access controller" in the DMA resource list under Computer Properties in DM is in fact the cascaded output of DMA controller #1. - Franc Zabkar -- Please remove one 'i' from my address when replying by email.

I had a 3.904 Gb backup to do, did it with Nero, in windows 98SE, and it took 93 minutes. I then fired up a livecd PClinux and burnt the same project in 10 minutes and 4 seconds. using K3b. Both times using LG 16x media and programs set to "max speed". Both programs reported they were burning at 16x So it has to be a driver problem. ................................. When you told me to delete drives cds and busmasters and etc in device manager, in safe mode, when I rebooted back to normal mode the computer asked me to reinstall a lot of stuff. I always gave /windows/inf as the source, and it seems happy with that. But so many VIA names in the drivers I wonder if I really got rid of them. If I refused to let it install stuff (by pressing cancel) it just froze.
Guest PCR Posted June 26, 2008 Posted June 26, 2008 Re: A hack, anyone, to turn on dma ? http://www.google.com/search?hl=en&q=TSSTcorp+CD/DVDW+SH-S182F++dma&start=10&sa=N Google has about 132 for "TSSTcorp CD/DVDW SH-S182F dma". I haven't read them all. Here is one... http://www.dvdplusvideo.com/dvdguide005.html Enabling Direct Memory Access or "DMA" for faster DVD copying That article is speaking of WinXP. It says... "For repeated DMA errors. Windows XP will turn off DMA mode for a device after encountering certain errors during data transfer operations. If more that six DMA transfer timeouts occur, Windows will turn off DMA and use only PIO mode on that device. In this case, the user cannot turn on DMA for this device. The only option for the user who wants to enable DMA mode is to uninstall and reinstall the device." Can it be similar in Win98? I see on glee's instructions you went the Device manager route to reinstall drivers. I'd think normally that to be enough. But how tough was it to install that DVD in the first place? Can you completely uninstall it so that it no longer appears in Device Manager at all-- then, reinstall it? | TSSTcorp CD/DVDW SH-S182F | CDROM | Chave do Registro: | HKEY_LOCAL_MACHINE\enum\SCSI\TSSTCORPCD/DVDW_SH-S182FS\MF&CHILD0001&PCI& VEN_1106&DEV_0571&SUBSYS_80ED1043&REV_06&BUS_00&DEV_0F&FUNC_0100 | Recursos Alloc: Nenhum | Recursos Forçado: Nenhum | Recursos Inicializar: Nenhum | Recursos Filtrado: Nenhum | Recursos Básico: Nenhum | Driver: CDROM\0000 | Data do driver: 5- 5-1999 That XP article also speaks of a Registry key.

It may not support your particular chipset, though. One other approach may be to read the values of the actual PCI registers that determine whether DMA is enabled or disabled. I use a program by H. Oda called Wpcredit: http://www2.tky.3web.ne.jp/~nrklv/soft/wpcre14.exe Select Edit -> Device and click your IDE Controller. I believe its Function number should be 1, but I'm not sure of its device number (could be 17). If your VT8237 southbridge chip is anything like earlier VIA chips, then offsets 50-53 will contain the UDMA/PIO settings for the four primary/secondary master/slave IDE devices. If you post the values of those bytes, then we could possibly make sense of them for you. For example, here is an excerpt from a VIA VT8231 datasheet: Offset 53-50 - UltraDMA Extended Timing Control ..... RW bit function --- ---------------------------------------------------------- 31 Pri Drive 0 UltraDMA-Mode Enable Method 0 Enable by using “Set Feature” command.......... default 1 Enable by setting bit-30 of this register 30 Pri Drive 0 UltraDMA-Mode Enable 0 Disable........................................ default 1 Enable UltraDMA-Mode Operation 29 Pri Drive 0 Transfer Mode 0 DMA or PIO Mode ............................... default 1 UltraDMA Mode If your solution requires turning on any of the above bits, then there is a program called Wpcrset that can do it for you automatically at every bootup. In fact I'm using it to tweak the memory settings in my SiS chipset. I get about a 10% improvement in my RAM benchmarks. Here are datasheets for two older (?) VIA southbridges: http://www.datasheetarchive.com/pdf/3640621.pdf (VT8231) http://www.datasheetarchive.com/pdf/3640622.pdf (VT8235M) - Franc Zabkar -- Please remove one 'i' from my address when replying by email.

Decoding the value of register 0x53, we have ... 0xF1 = 11110001b AFAICT, this means that UDMA mode is being set by this register rather than by the ATA Set Features command, UDMA is enabled, Pri Drive 0 Transfer Mode is UltraDMA Mode, an 80-pin cable is being used, and the Pri Drive 0 Cycle Time is 3T (= 22.5ns). Doing the same for register 0x52 (00010111b) suggests that there is no primary slave, the Pri Drive 1 Cycle Time is 9T (=default), and the cable is 80-pin. The value of register 0x51 (11100110b) is telling us that UDMA mode is being set by this register, UDMA is enabled, Sec Drive 0 Transfer Mode is UltraDMA Mode, a 40-pin cable is being used, and the Sec Drive 0 Cycle Time is 8T (= 60ns). Register 0x50 (00000111b) suggests that there is no secondary slave, the Sec Drive 1 Cycle Time is 9T (=default), and the cable is 40-pin. Maybe you could speed up your optical drive by experimenting with the Cycle Time bits in register 0x51? Or try using an 80-pin cable? - Franc Zabkar -- Please remove one 'i' from my address when replying by email.

Any difference? it uses the mscdrom.inf from 5-5-1999 I just went crazy, dropped to DOS, renamed my windows folder "badboy", reinstalled windows in "windows", and ---- the cdrom does not accept dma, the box is there , but will not stay ticked. So it is something quite native. The new windows did not even know the DVD existed, it was a clean install. So although samsung says the drive is compatible with windows 98, someone made a big booboo with the drivers. Either VIA or Samsung when they designed the hardware. I will have to boot linux for my backups. What I hate about K3b is that it does not support checking the compilation, also it knackers my long file names. If you are interested, I can grope around in /proc and see if linux is using any dma..... I'll do that :P

Guest MEB Posted June 28, 2008 Posted June 28, 2008 Re: A hack, anyone, to turn on dma ? Haven't scrolled back through this discussion [likely some of this was preented]:: http://downloads.viaarena.com/drivers/4in1/VIA_Hyperion%204IN1_V448release.doc SOME versions had bugs, some lacked support, some were specific, etc,, test installing various drivers would require ensuring the previous had been *completely* removed {particularly in the INF folder}. 98 supports DMA but may disable it if your 98 system fails certain tests. Specifically when the drivers: 1. query the motherboard chip set, 2. query the drive itself, and, 3. test a short pattern of disk reads and writes to see if they are reliable at DMA speeds. If any of the three or combination fail, DMA will be disabled upon reboot. After errors, driver or software, the system may downgrade [permanently]. Particularly true for newer OSs [XP, VISTA]. ONE WAY that WILL kill DMA is to attempt to read a badly burnt or scratched disk multiple times... another, errors during the copy/burn process There MAY be a difficulty between the default CDROM drivers supplied [default IDE INFs] and the actual drive when accessed. There MAY be BIOS issues, using ACPI in some BIOSs may allow DMA to be used if not already set. * It may depend upon other drives attached to the channel, try: DVD-RW as Device 0 (1st) as Master and the other CD-RW/hard drive as Device 1 (2nd) as Slave. You might try the potential fixes here: http://www.mdgx.com/98-2.htm#W98DMA - it starts at the VERY top of the DMA info, scroll down to see the help and potential fixes. Make sure you look at: http://download.microsoft.com/download/win98SE/Update/5638-6151/W98/EN-US/243450USA8.EXE - contains an updated esdi_506 You can find more DMA fix info here: MDGx Windows 98/98 SE + DOS 7.10 Tricks, Secrets, BUGs + FIXes http://www.mdgx.com/newtip98.htm - use find DMA on the page in the browser's search/find. Cleaning: And as I have previously posted, it might be advisable to open the drive case and look at the laser lens. When they get blocked [dust/dirt/hair/paper, whatever], smogged, or *smoked*, the system will downgrade speeds and abilities, as will burning software. Sometimes you can carefully blow them out, sometimes you have to CAREFULLY clean with a de-natured alcohol moistened q-tip... -- MEB http://peoplescounsel.orgfree.com -- _________ "Franc Zabkar" <fzabkar@iinternode.on.net> wrote in message news:do9664lnmd6sapkft6ug08ncsj4en3feut@4ax.com... | On Wed, 25 Jun 2008 21:30:50 -0300, Shadow <sh@dow> put finger to | keyboard and composed: | | >On Wed, 25 Jun 2008 17:47:23 -0400, "glee" <glee29@spamindspring.com> | >wrote: | > | >>"Shadow" <sh@dow> wrote in message | >>news:kia56414frgspmk6rfqrga8b32k74an5kc@4ax.com... | >> | >>Yes.
